Read up on the Runtime object. You can get a reference to it using getRuntime(), and use this reference to run external programs by using Runtime.exec().
Think of this as being able to use a shell within a program.
Runtime r = Runtime.getRuntime();
Process p = r.exec("java yournewprogram");
//now you have a process running yournewprogram
There are a few other details you may want to work out, read up on it.

Runtime() has private access in java.lang.Runtime

Please post the code in which you are trying to get and use the aforementioned Runtime object.
